The electronic transmission control gives a choice of three different operating strategies for the TTV transmission. MANUAL Depressing the accelerator pedal increases the engine rpm while operating the multifunctional lever varies the ground speed. In this instance, the TTVs are essentially comparable to a tractor with a mechanical gearbox but, due to their “infinite” ratios, have the great advantage of superb drive smoothness that is typical of CVT transmissions. Keeping the multifunction lever pushed forward or backward (for reverse or to decelerate) varies the speed continuously. On the other hand, short pulses on the lever allows you to vary the speed in intervals of 0.1 km/h from 0 to 15 km/h and intervals of 1 km/h for higher speeds. AUTOMATIC The best choice for operations in the field and for road transport. When the accelerator pedal is pressed, the tractor accelerates to the preset travel speed. The electronic control unit then keeps the speed constant, adjusting the engine rpm according to the changing load conditions.

PTO This mode automatically activates when the PTO is engaged, keeping the rpm constant regardless of the tractor’s ground speed. In all cases, the operator can constantly vary the ground speed using the accelerator pedal. In this way, the TTV overcomes the main limitation of conventional mechanical transmissions that do not allow you to adjust the driving torque to a different speed from the engine unless you make a gear change. This method is therefore ideal for equipment that must operate at a constant PTO rpm, such as round balers. 7
